Cannot join meeting via callback – GlobalMeet 4 Review

Since updating to iOS 11, I am no longer able to join the meeting via call back. When the voice prompts for me to “press 1 to join meeting”, the app does not recognize that I have pressed 1 regardless how many times I press. No issues with joining via data connection. Like I said, this only happened after I upgraded to iOS 11.
